Consider generating all schemas as part of the same json-schema file

[bruno-f-cruz]

Pros:

• Simplify serialization/deserialization
• simplify bonsai classes and namespaces
• Only requires one operator

Cons:

• Refactor workflows due to namespace changes
• No longer able to "mix and match" across tasks (which should be ok)
• More potential for naming clashes?

Notes:

For simplicity, the user would still be allowed to generate the jsonfiles individually. The only difference is that we would deserialize at the level of the individual schemas instead of the container for all 3
